I have a wireless network, with two laptops and two desktop systems. I get 100% signal strength throughout my house on the laptops, but when I moved a desktop system to the basement to attach to a MIDI keyboard, I got dismal signal strength (about 20%). A laptop right next to the system showed 100%.Enter the Belkin antenna. After removing the network card's antenna and attaching the Belkin, signal strength more than quadrupled, to 85%. That makes the internet connection usable again.I would have rated it a five if it would have given me 100% signal. What's the problem? The card? Planetary alignment? Who knows... But the Belkin was worth it!
